Hi, friends! I’m Hui Mei 👩💻, and today we will explore a classic yet often misunderstood concept in C++—the **inline function**. If you’re new to C++, you might be confused about this keyword: is it a “black technology” for performance enhancement or a trap that’s easy to fall into? In this article, I will analyze … Read more
In the world of C++ programming, resource management has always been a headache, especially when dealing with memory, file handles, and other system resources. Today, I want to explore a very important concept with you—RAII (Resource Acquisition Is Initialization). Through this article, you will understand how RAII helps us manage resources effectively, avoiding common memory … Read more
Handling files and paths is a frequent task in any programming language. In C++, we used to rely on platform-specific APIs (such as CreateFile on Windows or open in POSIX) to accomplish this. This approach was not only cumbersome but also required consideration of cross-platform compatibility issues. The good news is that with the introduction … Read more
Hi, friends! I’m Hui Mei! 😊 Today we are going to talk about a very useful tool in C++ — **std::async and std::future**, which make asynchronous programming simple and efficient. If you’ve ever struggled with issues like locks and callback functions in multithreaded programming, today’s content will surely open up a new world for you! … Read more
Hello everyone! Today we’re going to talk about std::future and std::promise in C++. With the rise of multi-core processors, asynchronous programming has become an important skill for developers to master. The std::future and std::promise introduced in the C++11 standard are great partners for handling asynchronous tasks, allowing us to complete asynchronous operations more elegantly. In … Read more
In C++, we often hear the term “exception safety”. It is not only about whether the program runs stably but also closely related to performance. The protagonist we are discussing today, noexcept, is a keyword closely related to exceptions. It can help us optimize program performance, but improper use may also create “hidden traps”. Today, … Read more
In C++, forgetting to release dynamically allocated memory is a common pitfall for beginners. To address this issue, smart pointers have emerged. The smart pointer std::shared_ptr allows multiple pointers to share the same memory and manages its lifecycle through reference counting, which is very convenient. However, std::shared_ptr is not infallible; it has a fatal flaw: … Read more
When writing C++ programs, we sometimes need to verify whether certain conditions are met, such as whether the array size is acceptable or whether template parameters are valid. If these issues are discovered at runtime, they can cause the program to crash unexpectedly. Static assertions (static_assert) are a compile-time tool provided by C++, which can … Read more
C++ memory management is a core topic in programming, involving complex concepts such as pointers, dynamic memory allocation, memory leaks, and memory fragmentation. C++ provides the ability to manipulate memory directly, which brings flexibility but also comes with higher complexity and the risk of errors. To aid in understanding C++ memory management, we will explore … Read more
